I attended a Human Centric Lighting (HCL) conference in Oslo last week. It was a nice recap as I have done research into the physiological effects of light on health. The speakers included Mariana Fugeiro and Mark Rea from the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute in New York. They are both well known researchers in the field of light and health. Their studies have shown that Human Centric Lighting has a significant influence on our health and well-being.

We know that light plays an important role in regulating the circadian rhythm of the body. Throughout the entire day our brain receives ‘light signals’ from the outdoor and indoor environment to regulate our biological clock. When the biological clock is set correctly to day-time, we feel energised, alert, motivated and ready for what we want to do and achieve today.

However regular lighting is purely designed to achieve good visibility. Whereas Human Centric Lighting takes into consideration that we need bio-dynamic lighting to meet our non- visual needs.

Lighting technology has advanced to the extend that we nolonger have to design static lighting solutions but our indoor lifestyle can be enhanced with dynamic lighting schemes. We at Leolightdesign have worked with bio-dynamic lighting for over 10 years and plan Human Centric Lighting solutions that can support our human circadian rhythm, enhance concentration, help prevent sleeping disorders and improve our overall well-being.

What I enjoyed while being at the conference was getting to try out their virtual reality demo applications using different human centric lighting solutions.
